Thanks for submitting your work here!

I think one major change that I would make is destructuring the props that you're passing on line 8 so it could look like {searchTerm, resetSearchTerm, searchLabel, etc...}. Since this didn't pass a few tests and we have a couple other pull requests refactoring this component, I'm going to close this for now. However, please feel free to check out the other issues!
